CRIB WITH MATTRESS FRAME AND SIDE PANELS SIMULTANEOUSLY MOVABLE INOPPQSITE VERTICAL DIRECTIONS Filed Aug. 27, 1948 3 Sheets-Sheet 3 FINVENTOR 8 SYLVIA B. Gowsnzm,

ATTORNEY engages and which will be hereinafter more fully described. Thesaid corner posts G2 are further securely held together, at oppositeends of the crib, by transverse members 2| (Fig. 3), each of whichconsists of a top rail 22, a bottom rail 23 and vertical bars 24 whichare fastened to the said top and bottom rails 22 and 23 respectively.Below the said bottom rail 23 there is secured a panel 25 which isattached at its'ends to the adjoining posts if, to the said bottom rail23 and to the upper side of the aforesaid frame I5.

A bracket and capping member 26 is attached to the upper end of eachcorner post i2 and is formed with a partial bore 21. A second bracketmember 28 having a bore 29 therethrough is also secured to the cornerposts (Fig. and a third bracket member 38 is secured to each of the saidcorner posts. The bracket 39 has a bore 31. The upper end of the saidcentral shaft section 20 has a contracted end portion 32 which rotatablyengages in the said bore 29 of the bracket 28 and is formed with asquared recess 53 within which a coinciding squared projection 54 formedupon the lower end of an upper shaft section engages. The upper end ofsaid upper shaft section 35 has a contracted circular projection whichfits into the said bore 2'! upon the bracket 25.

The contracted lower end of the said central shaft section 20 is alsoformed with a squared recess 36 within which a corresponding squaredprojection 3'! upon a shaft 38 is adapted to engage. The lower end ofthe said shaft 35 is con --tracted to form a circular projection 85thereon .of said corner posts l2, have formed upon their outerperipheral surfaces helical grooves 46 and engage through bores 4!formed upon the four projecting corners 42 of a mattress supportingframe 43. The said bores 4| have internally formed helical ribs whichare complementary to the said helical grooves upon the said shafts 25.It is obvious that when the shafts are rotated, in the proper direction,the said rotation will urge the said mattress supporting frame upwardlyfrom its lowermost position or downwardly from its uppermost position,when the said shaft is rotated in the opposite direction.

The aforesaid side drop panels, one upon each side of the crib, are eachformed with a top rail 44 and a bottom rail 45 connected by verticalmembers 56. The outer ends of the top rails of the said side drop panelsare formed with boss or knob 4'! having a bore 48 (Fig. 5); which isformed with a helical rib conforming to and engaging with a helicalgroove 49 upon the peripheral surface of the aforesaid upper shaftsection The bottom rails 45 of the said side drop panels are similarlyformed with a boss or knob 15f! having a bore 5| and a helical shapedrib conforming with and engaging a helical groove 52 upon the said shaft38. Thus when the shafts comprising the three sectional portions 29,

and 38 are rotated in the proper direction, the said mattress supportingframe 43 will move upwardly while the said side drop panels will movedownwardly as indicated by the dot-dash lines 53 and 5 respectively(Fig. 5) and by the full lines --in Fig. 2.

v By reversing the direction of rotation of the said -shafts 2d, 35 and38 the said mattress supporting :frame 43 and the said side droppanelswill move downwardly and upwardly respectively to resume theposition shown by the full lines of Figs. 1 and 5.

With the said mattress supporting frame and said side drop panels intheir respectively normal, lowered and raised positions, the saidactivating shafts may 'be rotated by manually depressing or raising thesaid side drop panels.

Upon the said side drop panels there are provided weight blocks 55 ofsufficient weight to counteract and balance the weight of the said thesaid motivating shaft mattress supporting frame and the friction of therotating shafts.

The said sectional rotating shafts are coupled by means of a transverseshaft 56 mounted at each end of the crib and upon the ends of whichthere is attached a bevel gear 51 coacting and meshing with a similargear 58 upon the lower end of each lower section 38 of the said rotatingshaft. Upon each of the said shafts 55 there is provided a locking wheel59 which is notched to receive the fin end 60 of an arm Bl which is inturn mounted upon a shaft 62 extending longitudinally across the lowerportion of the crib and rotatably mounted in the said cross rails 54 ateach end of crib and centrally thereof upon a cross channel 53. From thesaid shaft 52 there is attached an extending arm 64. terminating at itsouter end in a pivotal connection 65 at which point there is attached afoot pedal arm 53 (Figs. 1, 2, 3 and 4). A spring 61 is provided tonormally keep the locking member 60 in engagement with the said lockingwheel 59. When the said fin end 66 is in engagement with the saidlocking wheel 59, the said mattress supporting frame 43 and itscoordinating parts are held immovable. However. by pressing the footpedal down the said locking wheel 59 is released and the parts may beoperated. It will be noted upon the drawings, Figs. 1, 2 and 3 that thepedal 66 passes through a slot 61 in a depending plate 68 and that theslot 61 is formed with a broadened lower cut out to form ledges 69 underwhich the said pedal may be moved to hold same down.

In Figs. 9 and 10 there is shown a crank handle 10 secured upon asquared section II formed upon the upper end of the shaft 35. The outerend of the said crank handle 10 is provided with a pivotally attachedL-shaped portion comprising a hand hold or knob 12 and a finger 13 whichis adapted to engage in a slot 14 formed upon the cap member 26. Withthe knob 12 in the up right position shown in Fig. 9, the handle may beused to raise or lower the said mattress supporting frame and thecoacting side drop panels. By turning the said knob 12 about its pivotalconnection the finger 13 may be brought into engagement with the slot'74 and lock the parts against movement. The aforesaid shafts 55 (one ateach end of the crib) may be connected by means of a bevel gear 16 uponone end of a shaft H, having end bearings on the cross rails I4 andbearing 18 upon the channel member 63 and bevel gears similar to bevelgears 15 and 15 at the opposite end of the said crib.

In Fig. 4 a portion of a mattress 19 is shown resting upon aconventional spring mounted upon the said mattress supporting frame 43.

In the drawings Fig. 5, the helical grooves 45 in the central section2!! of the three sectioned motivating shaft are cut in such manner thatwhen is given clock-wise rotation, the said grooves 40, when consideredas imparting a downward movement to its coordinating mattress supportingframe, will travel in a clock-wise direction while the helical grooves49 in the upper section 35 and the helical grooves 52 in the lowersection will at the same time travel in a counter clock-wise directionto raise the said side drop panels, or vice versa.

Iclaim:

1. In a crib, an enclosure frame, comprising end panels, corner posts,connecting cross rails and side rails, a vertically adjustable mattresssupporting frame, vertically adjustable side drop panels, threadedshafts each having oppositely threaded portions rotatably mounted uponsaid enclosure frame in close juxtaposition to said corner posts andengaging through threaded sockets in the said vertically adjustablemattress supporting frame and the said vertically adjustable side droppanels to simultaneously and vertically move in opposite directions, thesaid mattress supporting frame and said side drop panels when the saidthreaded shafts are rotated.

2. A crib as defined in claim 1 in which a looking means is provided tomanually hold the parts immovable and a foot pedal actuating means torelease the said locking means.

3. A crib as defined in claim 1, in which a crank handle is attached toone of the said threaded shafts to afford a means for manually rotatingsaid threaded shaft.

weights are included upon the said side drop panels to counter balancethe excessive weight of the said mattress supporting frame and overcomethe friction of the said threaded shafts in the said threaded sockets.
